Matt Arsenault 06c192d454 OpaquePtr: Bulk update tests to use typed byval 
Upgrade of the IR text tests should be the only thing blocking making
typed byval mandatory. Partially done through regex and partially
manual.

Artem Belevich 9f97dcb018 [NVPTX] Make sure we adjust alignment at all call sites 
.. including calls from kernel functions that were
ignored by mistake before.

Artem Belevich 052b1ed2fd [NVPTX] Force minimum alignment of 4 for byval arguments of device-side functions. 
Taking address of a byval variable in PTX is legal, but currently runs
into miscompilation by ptxas on sm_50+ (NVIDIA issue 1789042).
Work around the issue by enforcing minimum alignment on byval arguments
of device functions.

The change is a no-op on SASS level for sm_3x where ptxas already aligns
local copy by at least 4.
